Product DescriptionProduct DescriptionRubber Inflated Culvert Balloon for Hollow Slabs The rubber inflated culvert balloon, also known as the bridge inflatable core mold, is an expandable and contractible cylindrical bag made of rubber with a fiber-reinforced layer, featuring excellent tensile strength, elasticity, and air-tightness. It is primarily used to form cavities in concrete components. When manufacturing hollow components, the inflatable core mold is placed in the middle of the component and is expanded by injecting compressed air. The inflated core mold can withstand the pressure of concrete, thus effectively replacing traditional wooden, bamboo, and steel molds. When in use, simply open the valve, and the airbag will deflate, making it easy to remove from the cavity.Category Based on the shape of the rubber inflated culvert balloon, it can be divided into the following common types: rectangular, round, regular octagonal, flat octagonal, reducer, and elliptical.Types of inflatable rubber airbagsSpecificationRound φ220 mm × 8.5 mRound φ260 mm × 10.5 mRound φ360 mm × 14 mRound φ390 mm × 14 mRound φ520 mm × 17 mOctagonal φ360 mm × 760 mmReducer φ360 mm × 600 mm × 11 mOctagonal φ460 mm × 760 mmReducer φ460 mm × 600 mm × 14 mOctagonal φ560 mm × 760 mmReducer φ560 mm × 600 mm × 17 mOctagonal φ710 mm × 760 mmReducer φ710 mm × 600 mm × 21 mOctagonal φ560 mm × 780 mm × 17 mOctagonal φ710 mm × 800 mm × 21 mOctagonal φ460 mm × 550 mm × 14 mOval φ360 mm × 520 mm × 17 mOval φ360 mm × 480 mm × 14 mInstallationRequirements for the rubber inflated culvert balloon for hollow core precast beams: *When installing the rubber inflated culvert balloon, the length specifications of the hollow core precast beams are usually 8 m, 10 m, 13 m, 16 m, 20 m, 25 m, and 30 m; lengths exceeding 30 m are generally not designed as hollow core beams. *For culvert balloons below 13 m in length, the inner culvert balloon is generally made of rubber; for culvert balloons above 16 m in length, there is more flexibility in the choice of inner culvert balloons, which can be rubber, wood, or steel. *During the construction process, the rubber inflated culvert balloon is placed inside the rebar cage, inflated with compressed air to form the desired cavity shape, and withstands the pressure during concrete pouring. After use, it can be deflated and removed from the cavity, allowing for multiple reuse.Product DetailsPackaging & ShippingCompany ProfileFAQ1.When can I get the quotation?A:We usually quote within 24 hours after we get your inquiry.2.How long can I expect to get the sample?A:The samples will be ready for delivery in 5-10days.
